This time, she will be the subject of a documentary chronicling her battle with rare, terminal brain cancer.

Former Today co-anchor Meredith Vieira will be host of the hour-long program produced by NBC News' Peacock Productions to air on the network in prime time. The broadcast date has yet to be announced.

In early March, Harper learned that a recurrence of her 2009 lung cancer spread the disease to the membrane surrounding her brain. Since then, she allowed camera crews access to doctors' visits, surgeries, reunions with friends and more to help share her story, according to a release from NBC.

"This first-person account captures Harper's raw, emotional and hopeful journey as she goes through experimental treatments and lives each day to the fullest with her husband Tony Cacciotti and their daughter Christina," says NBC.

A week after announcing her condition, Harper told USA TODAY that she was "trying to live every moment as much as I can."

"I can't say it's terminal. I'm saying it's incurable so far, but we're all terminal. No one is getting out of this alive," she said. "The key is, don't go to the funeral until the day of the funeral."
